GEORGE A. RAMSEYER, OF DOBBS FERRY, NEXV YORK.

PIANO-STOOL.

SPECiFiCA'ITON forming part of Letters Patent No. 282,926, dated August7, 1883.

Application tiled April J3, 1883. (No model.)

To aZZ whom it may. concern.-

' of Dobbs Ferry, in the county of Westchester and State of New York,have invented a new and Improved PianoStool, of which the following is afull, clear, and exact description.

This invention relates more especially to that class of piano-stoolsknown as ottoman or double screw stools, and seeksto improve theconstruction of stool covered by my patent numbered 186,7 57 and dated January 30, 1877.

The principal object of my present invention is to cheapen and rendermore practical the mechanism used for elevating the stoolseat.

Another object is to devise such arrangement and construction of theparts of the stool as will make the stool stauncher, and at the sametime furnish greater latitude for ornamentation and design thanheretofore.

. Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional elevation of my new and improved piano-stool,taken on the line w w of Fig. 2, and Fig. 2 is a broken end elevation ofthe stool.

A A are the standards of the stool. These are formed or provided withthe side legs, a a, that rest upon the floor, and are tied together,near their lower ends, by the bar B, that is secured at its ends to thestandards by the bolts 1) I) and nuts. 0 c, placed in the slots (Z d; orthis bar might be secured by any other suitable means. The upper ends ofthe standards A A are formed with the slots ff, in which the webs g g ofthe brackets O C fit. The seat D of the stool is secured upon the upperedges of the brackets O O, and through the longitudinal center of theseat is passed the shaft E,which is provided at its ends with the knobsh h, and has secured to'it, in a suitable recess formed in the seat, thebeveled cogwheels 2' F F are the vertical screw-shafts for raising andlowering the seat D. These shafts pass through the screw-threadedsleeves G G, that are secured by screws or otherwise to the inside ofthe standards A A, and are adapted to be revolved from the shaft E forraising and lowering the seat through the medium of the beveledcog-wheels 'i 23, secured upon their upper ends, that mesh with thecog-wheelsi t. The screw-shafts F F and sleeves G G are con cealed fromview by the central apron, H, which is secured to the under side of theseat 'D, and is recessed at its ends, as shown at j j,

to inelose the said shafts and sleeves, as will upper ends thescrew-shafts F F are reduced in size to form the shoulders e e, and uponthese reduced portions are placed the journal-boxes J J, which aresecured by the screws k k to the apron H, as shown in Fig. 1, the apronbeing suitably recessed to receive the boxes. Thus arranged the apron H,besides serving to conceal the operating mechanism, braces and stiffensthe structure, holds the screw-shafts properly, and causes the seat,apron, and shafts F F to always move together without any cramping orbinding of the parts.

The brackets C C fit snugly against the side edges of the standards A A,and thus serve as braces to the seat D, and also as guides to the seatin its up-and-down movement, and these brackets O O, and also the apronH, are suited for elaborate design and ornamentation.

\Vith this construction of the stool it will be seen that all boring ofthe standards is avoided, and that the use of shields and screwtubesplaced in the bores of the standards, as in the above-mentioned patent,is avoided, which is a great advantage, since such screw= tubes andshields are expensive, and liable to get out of order. Besides, by thisconstruction the stool is made stronger and better in every ,way than bythe old construction, and

, may be made far more ornamental.

Instead of securing the journal-boxes J J to the apron H, it will beunderstood that be clearly understood from Fig. 1. At their they mightbe secured to the under side of the 5 seat D and not depart from theprinciple of my invention, since by such arrangement the screw-shaftswould be held as firm as by the arrangement shown.

Having thus described my invention, I claim as new and desire to secureby Letters Pate11t- In a piano-stool, the supporting-frame havingscrew-bearings G G, attached on the inside of standards A, incombination with the movable seat, having bearings, as set forth,

the apron H, attached thereto, guiding means IO interposed between theseat and supportingframe, screws F F, jonrnaled .in bearings of theseat, and means for actuating said screws,

as and for the'purpose described. 5
